Application Specific Clock/Timing Procurement Notes

This component is officially listed as End-of-Life (EOL) by Renesas Electronics Corporation. Verification of availability should focus on remaining stock or authorized distributors holding legacy inventory. No new production is expected. Compliance data confirms RoHS3 adherence and MSL level 3 classification.

Application Specific Clock/Timing Selection Notes

Engineers replacing this part must account for its discontinued status. Design reviews should verify if the 444MHz maximum frequency and 48-SSOP footprint meet current requirements. Alternative solutions may require re-evaluation of the timing architecture and physical board space constraints associated with the BSSOP package width.

Application Specific Clock/Timing Part Context

The 953002DFLF is part of the broader TCH family, which includes variants like the 950201AFLF. These devices were specifically engineered to manage complex clocking requirements for high-performance computing platforms based on Intel architectures during their respective design cycles.

Application Specific Clock/Timing Replacement Considerations

As an EOL component, direct substitutes are not officially confirmed in public documentation. Engineers should consult Renesas support for qualified replacement recommendations or evaluate modern universal frequency translators.
